Not to start an argument, since i respect the bucks for their pioneering work in cardistry, but seriously, everytime someone asks a question, the answers can always be found in the Trilogy..... there are so many other and better sources to learn from then the Bucks.....
Just off the top of my head, i remember the "nestorizer" gimmick and dvd having some great card productions, many of which dont require the gimmick at all. plus the gimmick is usefull for some things.
